Humming noise at rear drivers what is it and how can i fix it.

Hello, have you checked the tire condition? Is the tread feathered in any way -- meaning, if you slide your hand along the tread surface, is it bumpy? This is often where noise comes from while driving - the most common cause. Before all that, though, I'd return to the dealership you purchased the vehicle from and share your concerns and let them try and resolve it for you. You JUST bought the car. There's some obligation here, even if it's not a legal obligation, most sellers will see it as the "right thing to do" to resolve a concern.
